OneNote for the Web Is Losing Loop Components in September

Microsoft is removing Loop components from OneNote for the web, with support scheduled to end by mid-September 2026. The company announced the change through Message Center post MC1454385.

The retirement only affects the web version of OneNote. OneNote for Windows will continue supporting the full Loop component experience.

Loop components will become links

Loop components are shareable and editable pieces of content that stay synchronized across Microsoft 365 apps. If someone edits a component in one location, the changes automatically appear everywhere else that component is used.

Once Microsoft completes the retirement, OneNote for the web users will no longer be able to insert new Loop components.

Microsoft will not delete existing components. Instead, OneNote will convert them into links that open the corresponding Loop page, allowing users to continue accessing the content.

OneNote for Windows keeps full Loop support

Users who rely on Loop components inside OneNote will need to move to the Windows app if they want to keep inserting and working with them directly.

Microsoft says the change will streamline the OneNote for the web experience while maintaining access to existing Loop content.

IT admins cannot block the change

Administrators cannot prevent or delay the retirement.

Microsoft recommends that organizations inform affected users, update internal documentation, and direct employees who still need Loop components to OneNote for Windows.

The change adds another Microsoft 365 feature retirement to the calendar. Microsoft is also retiring the COPILOT() function in Excel.

Separately, Microsoft has confirmed an issue where Copilot is missing from Classic Outlook for some users.
